African histoplasmosis in a child in Guinea: About a case

African histoplasmosis is a rare deep mycosis caused by two varieties of Histoplasma capsulatum (capsulatum and duboisii). We report a case of histoplasmosis in an immunocompetent child. 6-year-old female patient, hospitalized for poor general condition, fluctuating inflammatory swelling of the lower limb evolving for 4 months. The clinical examination revealed in an altered and febrile patient, papulo-nodular lesions of variable size, fluctuating in places, disseminated umbilical predominantly on the trunk, the root of the upper and lower limbs. There were also axillary and inguinal lymphadenopathy and osteo-articular involvement. X-ray of the right lower limb revealed osteomyelitis. Histopathology of the biopsied nodule confirmed African histoplasmosis. The rarity of African histoplasmosis in our country corroborates current data from the literature, however this could also be due to an underdiagnosis often influenced by self-medication.
